What a Extreme Heat Warning means
Dangerously hot conditions are expected or occurring: a heat index or temperature high enough to threaten life, often for several days and with little relief overnight.
What to do during a Extreme Heat Warning
Stay in air conditioning where possible (cooling centres if not), avoid outdoor work in the heat of the day, and know the signs of heat stroke: confusion, hot dry skin, loss of consciousness. Call 911.
Watch vs warning vs advisory
A watch means the ingredients are in place and the hazard is possible: be prepared. A warning means the hazard is happening, imminent or very likely: act now to protect life and property. An advisory is for less severe conditions that are still a nuisance or risky, and a statement is information that falls below those levels.
The companion product to the Extreme Heat Warning is the Heat Advisory, with 1 active now.
